Apple updates Xcode to support 10.8.3, squashes bugs

Apple on Saturday released a minor update to its app-building software for OS X and iOS, Xcode -- now at version 4.6.1. The most important addition to the program is support for OS X 10.8.3, with a corresponding update to the OS X SDK. It also fixes two specific issues: one where ARC-enabled apps would not launch on Snow Leopard (OS X 10.6.x), and a performance regression issue in the Analyze operation. The update to the free app is available exclusively on the Mac App Store, where it has been located since v4.6.
This is the first update to Xcode since version 4.6 was released in January, and included significant new features including better compiler warnings, deeper cross-function static analysis of Objective-C and C++ code, a reduced number of indexing passes and more accurate code-completion heuristics. It requires OS X 10.7.4 or higher to run, and app submission to the Mac or iOS app stores requires membership in the appropriate developer program, which costs $99 per year.
